摘要
Abstract
Low - voltage power line carrier communication (LV - PLC) has become an important mean of local communication in the undergoing China' s smart grids. But the poor environment on the low voltage power line has a bad effect on the performances of LV - PLC, measuring and understanding of the power line channel characteristics become vital. In view of the existing situation of the narrow - band LV - PLC widely being used in the remote power - meter reading system, the paper provides field measurement methods of the impedance and attenuation characteristics, and implements a field measurement on the selection of some typical distribution networks, then compares and summarizes impedance and attenuation characteristics measured in the frequency range of 80 ~ 500 kHz. A practical reference is provided for the study of real environments of the LV - PLC in this paper.关键词
